Genus
Common name: Sea Urchin
Scientific name: Lytechinus
Lytechinus is a genus of sea urchins in the family Toxopneustidae. Members of this genus are known for their distinctive, often brightly colored spines and globular bodies. They play a role in the reef ecosystem by grazing on algae, which helps prevent overgrowth that can smother corals. Hobbyists appreciate them for their algae-eating habits and their ability to help maintain clean rock surfaces. They should be kept in tanks with plenty of live rock and algae for grazing. It's important to monitor their spine health and ensure they have enough food, as they can starve if algae levels are too low.
